PAINT COMPOUND.

SPECIFICATION forming part of Letters Patent No. 394,566, dated December 18, 1888.

Application filed December 12, 1887. Serial No. 257,660. (No specimens.)

To all whom, ii may concern.-

Be it known that I, AARON M. FRENCH, a citizen of the United States, residing at Bercsford, in the county of Union, Dakota Territory, have invented certain new and useful Improvements in Paint Compounds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to compounds for painting surfaces of wood and iron to preserve them from decay and rust.

This invention consists in the novel combination of the ingredients, which are compounded and mixed together in the manner and proportions hereinafter fully described and claimed.

In carrying out the invention a mixture is first made consisting of mineral-brown, eight pounds; litharge, two pounds; hydraulic lime, four pounds; carpenters glue, two pounds, and two gallons of water.

The glue is first dissolved in the water, and then the other ingredients are stirred into it.

A separate mixture is also made, consisting of coal-tar, five gallons; gasoline, two gallons, and asphaltum varnish one pint. These ingredients are thoroughly mixed together and then added to and thoroughly incorporated with the first-described mixture. This is the paint compound which is most desirable for general use on wood and iron. The proportions of the ingredients may be varied to some extent to adapt the compound to special uses. For engine smoke-pipes, asphaltum and litharge may be used in equal proportions and mixed with onehalf pint of turpentine. For the floors of dwelling-houses a mixture containing two pounds each of mineral-brown and litharge, with one pound of glue dissolved in water, may be used. (are must be taken that the floor is free from grease before the paint is applied.

I am aware that it is not new to make a paint which has hydraulic cement and coaltar for its basis when mixed with mineral coloring-mattcr, and I do not claim the admixture of these ingredients; but prior to my invention these ingredients have been mixed with some oleaginous material, coal-oil and linseed-oil being often employed.

In carrying out my invention I use no oil whatever. It is consequently much cheaper, it dries quicker, and when the above-stated proportions and ingredients are adhered to it presents a very tine appearance.

\Vhat I claim is- A paint consisting of coal-tar, gasoline, asphaltum varnish, litharge, mineral-brown, hydraulic lime, glue, and water, compounded togethersubstantially as and in the proportions hereinbefore set forth.

In testimony whereof I a flix my signature in presence of two witnesses.

AARON M. FRENCH.
